Martin Hans Christian Knudsen (15 February 1871 in Hasmark on Funen – 27 May 1949 in Copenhagen) was a Danish physicist who taught and conducted research at the Technical University of Denmark. He is primarily known for his study of molecular gas flow and the development of the Knudsen cell, which is a primary component of molecular beam epitaxy systems. Knudsen received the university's gold medal in 1895 and earned his master's degree in physics the following year. He became lecturer in physics at the university in 1901 and professor in 1912, when Christian Christiansen (1843–1917) retired. Read more on Wikipedia
